The International Day of Clean Energy is observed worldwide every January 26. This United Nations observance was established to highlight the environmental impact of fossil fuels and promote the transition to clean energy sources. It aims to reduce reliance on fossil fuels, which are responsible for nearly 90% of global carbon dioxide emissions, and to encourage the adoption of renewable energy sources such as solar, wind, hydroelectric, and geothermal energy. The date commemorates the founding anniversary of the International Renewable Energy Agency (IRENA), an organization dedicated to advancing the sustainable use of renewable energy. The ultimate goals of this observance include cutting carbon dioxide emissions by half by 2030 and achieving zero emissions by 2050 to combat climate change.
